public static addListener(listener:Object) : Void
Detects when a SWF file is resized (but only if Stage.scaleMode = "noScale"). The addListener() method doesn't work with the default movie clip scaling setting (showAll) or other scaling settings (exactFit and noBorder).
To use addListener(), you must first create a listener object. Stage listener objects receive notification from Stage.onResize.
listener:Object - An object that listens for a callback notification from the Stage.onResize event.
This example creates a new listener object called stageListener. It then uses stageListener to call onResize and define a function that will be called when onResize is triggered. Finally, the code adds the stageListener object to the callback list of the Stage object. Listener objects allow multiple objects to listen for resize notifications.
this.createTextField("stageSize_txt", this.getNextHighestDepth(), 10, 10, 100, 22);
var stageListener:Object = new Object();
stageListener.onResize = function() {
stageSize_txt.text = "w:"+Stage.width+", h:"+Stage.height;
};
Stage.scaleMode = "noScale";
Stage.addListener(stageListener);
onResize (Stage.onResize event listener), removeListener (Stage.removeListener method)
